The purpose of this study was to propose a simulation method for pole vault jump motion to reduce computing time compared to conventional pole vault simulation. The whole-body was modeled as a virtual rigid body, and the pole was modeled as rigid bodies connecting to its adjacent segments with rotary spring elements. The equation of motion of the virtual rigid body was derived under the condition where the forces exerting on the pole grip act on each hand. An equivalent stifmess matrix at grip-end of pole was derived from the joint stifmess matrix to calculate pole reaction force and moment exerted on the virtual rigid body as the external force and moment.
